Comment(by karsten):

 I think I found the problem:

 https://gitweb.torproject.org/karsten/tor.git/commitdiff/c69c0983da4353bc4d5b3ad70ab9f1b8bd9bf5de

 In that particular line we read n_read bytes on a connection and need to
 decrement the bucket counters of the linked connection. I think we need to
 consider these bytes as written bytes on the linked connection, not read
 bytes.

 This logic seems to work for tunneled directory connections (OR conn ->
 Exit conn -> Dir conn; Exit and Dir conn are linked). Can someone confirm
 that this also works for linked connections in general?

 Attached you'll find a graph with more plausible results.

 See updated branch dirbytes in my public repository. If others agree, this
 patch can be merged into master.
